Answer:

Numerous techniques,1 technologies,2 and planning measures3 are available to address the issue of shoreline erosion, with most methods primarily intended to protect property from shore erosion caused by wave attack. Other erosive forces at the regional and local scale may affect the site’s geology and geomorphology, as described in Chapter 2, and some methods are specific to these forces. This chapter provides an overview of techniques and technologies commonly used to address erosion, followed by a discussion of important design elements and criteria that should be considered in selecting an approach to address erosion on sheltered coastlines.

Answer:

The correct answer is - natural selection or more precisely adaptive radiation.

Explanation:

Adaptive radiation is the process in the evolution of an animal or organism into different types of species or types specialized to fit different environmental conditions. These are depend on the various condition like food availablity or weather or any environemnt condition. It is the part of the natural selection that involves adapting the beneficial traits into genome of an organism over time period.

In galpago finches they are adapted different morphological condtions, based in food availblity in the particular environments even they had same ancestor is the best example of the adaptive radiation.

Answer:

The half-sets of genes contributed by sperm and egg restore a whole set of genes in the offspring. Mendel found that different gene combinations from the parents resulted in specific ratios of dominant-to-recessive traits. ... This is Mendel's famous 3 to 1 ratio.

Answer:

the upper layer of the Earth's mantle

Explanation:

Not the ocean, impossible to be in top of the core, not in the air

The modern model of the Plate Tectonic Theory suggests that the continents and the major tectonic plates drift slowly on the Earth's core. The Earth's surface is divided in the many layers.

The shape of the Earth is said be oval where the planet is little bent over the sides but seems round. The question seems to be controversial.

Earth's outer surface is the outer layer of the planet which is made up of many layers and this is called as lithosphere where the several plates glide over the surface.

The rocky surface of Earth made up of several layers glide over one another and make the surface a little uncomfortable. The gliding causes a movement of tectonic plates that leads to earthquake.

The gliding theory has many concepts related to it. The plates are acting like a hard plates in comparison to the Earth's plate.

Therefore the correct answer is the upper layer of the Earth's mantle.

Answer:

In bioethics, the ethics of cloning refers to a variety of ethical positions regarding the practice and possibilities of cloning, especially human cloning. While many of these views are religious in origin, some of the questions raised by cloning are faced by secular perspectives as well. Perspectives on human cloning are theoretical, as human therapeutic and reproductive cloning are not commercially used; animals are currently cloned in laboratories and in livestock production.

Advocates support the development of therapeutic cloning in order to generate tissues and whole organs to treat patients who otherwise cannot obtain transplants, to avoid the need for immunosuppressive drugs, and to stave off the effects of aging. Advocates for reproductive cloning believe that parents who cannot otherwise procreate should have access to technology.

Opponents of cloning have concerns that technology is not yet developed enough to be safe, and that it could be prone to abuse, either in the form of clones raised as slaves, or leading to the generation of humans from whom organs and tissues would be harvested. Opponents have also raised concerns about how cloned individuals could integrate with families and with society at large.

Religious groups are divided, with some opposing the technology as usurping God's place and, to the extent embryos are used, destroying a human life; others support therapeutic cloning's potential life-saving benefits.

Cloning of animals is opposed by animal-groups due to the number of cloned animals that suffer from malformations before they die, and while meat of cloned animals has been approved by the US FDA, its use is opposed by some other groups concerned about food safety.

Answer:

The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurones, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. This means that communication is faster when using the nervous system.

wym

Explanation:

Answer:

The muscle that makes up the heart is called the cardiac muscle. It is also known as the myocardium. The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body. The interossei muscles begin between the bones of the hand. There are four dorsal and three palmar interossei muscles. While all interossei bend the MCP joints, the dorsal interossei allow us to spread our fingers away from each other. The palmar interossei pull our fingers together.
